• On Memorial Day weekend, I found my boat having an overheating issue. I suspected a bad impeller and went to Frentress Lake Marine looking for a new impeller. After visiting with Jeremy for a few minutes, he convinced me that I most likely needed a new raw water pump and not just the impeller. I pulled my pump out and he was right!! The impeller (that I had just replaced this spring) was still in perfect condition, but the pump housing itself was worn. Just like he said. Frentress had the new pump in stock and at a fair price (I know what cost is on them). I also discovered that the pulley on these pumps is pressed on. I did not have the tools to remove and reinstall the pulley. Jeremy took care of transferring the pulley for me at no extra charge, on a Saturday, close to closing time. They are very busy there, but they still take the time to help you out. I'm very pleased to do business with them. Matt Johnston, IA
  • Sarah and I have been Frentress Lake slip owners since 2004. Ted, Tim, and Jeremy have done a super job of running the marina with numerous improvements and service. This marina is the best-kept secret in the area. The new pump out station, new gas and diesel fuel tanks, and now the new showroom are a few examples of major improvements. We feel that our boat is safe and secure and the area is just beautiful. Jack Jack Dubuque, IA
  • We could not be happier with Frentress. They were extremely accommodating and treated us with all of the attention and professionalism you would want and expect. Jeremy was particularly helpful and went out of his way to assist us in the purchase and equipping of our boat. Our Manitou is everything we expected it would be. We would recommend Frentress to all of our friends. Craig and Holly Cedar Falls, IA
  • We enjoyed another great buying experience with Ted and Jeremy. It was a big decision for us and they were always willing to take us to the showroom to look at our new boat and answer our questions. We love our new Monterey 204FSX!! It is a beautiful boat and drives like a Cadillac. My wife had cold feet on the day of purchase but after I saw the smile on our boys and Alison's face on our first ride, I knew we made the right choice! I would recommend Frentress Lake Marina to anyone in the market for a boat. They offer a Friendly, knowledgeable, and no pressure buying experience. Rob and Alison Dubuque, IA
  • We drove 362 miles one way to purchase a 5th wheel Frentress had taken in on trade. I spoke with Jeremy several times before making the trip and the unit was exactly as described, we couldn't be happier. Jeremy and Ron went the extra mile in 10-degree weather to get us hooked up and on our way. We have two boats so I took the time to tour the facility. They have a first class shop and equipment, extensive parts and accessory inventory, all clean and in good order. Wed recommend Frentress Marine Center to anyone looking to purchase a new or used unit or needing service work. Their staff is experienced and knowledgeable. They really go out of their way to make sure your needs are met Randy and Joan Columbia, IL
